I would look there too but I used to clear mine with a screwdriver.

I turned off the pump and then the water valves to house - done to

Absent mindedly, I opened the valves to the house, but neglected to
power the pump. Used up all water in the tank to the maximum before
discovering the error (hours later), where I powered the pump.

Here's the problem, since this time (and this was months ago), a
shower will bring me a trickle when the tank has emptied, sucking in
air to the plumping and about 30 seconds later the cut-in signals to
the pump to start up, where pressure is immedietly rendered, tank
refilled and life is good again.

I haven't yet tried to verify that the tank pressure (empty of water)
is set at 2psi below cut-in (38) of the 40-60 cut-in/cut-out settings.

Looking for the experienced members of this group, to give me their
experience on whether the fact that I completely dispelled the water
in the tank may have caused my problem, or if it might be more serious
in nature likely a bladder rupture. I don't have a cycle on / cycle
off problem obviuosly. Just the opposite, i have a late restart.

thanks,

I can see no way that running the tank fully empty did any harm.

I had the "delay" before teh pump would kick in bit. Traced it down
to an almost totally blocked riser pipe to the pressure switch. It
would take awhile before the change in pressure reached the switch.
Cleaned the pipe, problem cured.

Turn off the power, disconnect the wires to the switch (note where
they go!), unscrew switch, unscrew pipe and look at it. I had to take
a drill bit to ream out the crud in the pipe.
